Since you know so much about panbabylonism, you know that it was never widely accepted, confined mainly to Germany for a short period during the early 1900s.

Convenently you're leaving out this part.

The ideas presented within its framework still carry importance in mythological studies, due to similarities between myths in the comparatively young Bible and much older myths from ancient Mesopotamian mythologies.

And conveniently you haven't looked at the bibliography provided at the bottom of the page, which isn't about panbabylonism but about the actual myths in question.
